EVACUATION HATCH FITTING STRUCTURE AND FITTING MEMBER

To provide an evacuation hatch fitting structure capable of reducing a step part which is formed when an evacuation hatch is installed on an outdoor floor part, as much as possible, for improving appearance of the outdoor floor part where the evacuation hatch is installed, and improving safety.SOLUTION: There is provided an evacuation hatch fitting structure for an evacuation hatch 20 installed on an outdoor floor part 30, the evacuation hatch 20 is installed on the outdoor floor part 30 through a fitting member 10. The fitting member 10 comprises: a cylindrical part 11 which is fitted to an opening 30a formed on the outdoor floor part 30; and an outside protrusion part 12 which protrudes outward from the cylindrical part 11 and mounted on the outdoor floor part 30. The evacuation hatch 20 comprises a flange part 22 which protrudes outward. The outside protrusion part 12 is arranged between the outside floor part 30 and the flange part 22, and a protrusion dimension of the outside protrusion part is shorter than a protrusion dimension of the flange part 22.SELECTED DRAWING: Figure 2 【課題】避難ハッチを屋外床部に設置することにより形成される段差部を極力小さくすることで、避難ハッチが設置された屋外床部の見栄えを良くするとともに安全性の向上を図る。【解決手段】屋外床部３０に設置される避難ハッチ２０の取付構造であって、避難ハッチ２０は、取付部材１０を介して屋外床部３０に設置されており、取付部材１０は、屋外床部３０に形成された開口部３０ａに嵌め込まれる筒状部１１と、筒状部１１から外側に張り出して屋外床部３０に載せられる外側張出部１２と、を備えており、避難ハッチ２０は、外側に張り出して設けられるフランジ部２２を備えており、外側張出部１２は、屋外床部３０とフランジ部２２との間に配置され、フランジ部２２よりも張出寸法が短く設定されている。【選択図】図２
